This platform serves complex, versioned data models to React and Angular UIs, meeting enterprise needs for security, scalability, and maintainability.Key achievements include:• Security & Access Control: Designed RBAC API handlers with OAuth/JWT authentication, federated role-based authorization (Auth0, Entra, internal DB), per-resource validation, and field-level response shaping — ensuring precise, least-privilege data exposure.• Architecture & Design: Applied Domain-Driven Design to refactor core data models for better interoperability across backend services and integrations.• Operational Excellence: Delivered context-aware request tracing, D3-based performance visualization, and structured logging/alerting with DataDog and OpsGenie to improve observability and incident response.• DevOps & Reusability: Built CI/CD pipelines exporting shared API/component/validation libraries (Zod, JSON Schema) for multiple frontend teams, promoting consistency and speed.• Team Leadership: Mentored engineers in TypeScript, NestJS, and system design principles; championed peer review, automated testing, and early adoption of AI-assisted development tools to boost velocity.Technical Domains:• Languages & Frameworks: TypeScript, Node.js, Scala, Java, NestJS, TypeORM, and React.• Architecture & Cloud: Microservices, Serverless, Azure (Azure Functions, EventBus, Blob Storage), AWS (EC2, RDS, DynamoDB, CloudFront, SQS/SNS), IaC with Terraform.• DevOps & Tools: Azure DevOps, GitHub, Docker, Kubernetes, DataDog, OpsGenie, Jest and cypress automated testing, CI/CD.• Databases: PostgreSQL, SQL Server, Snowflake• Security: OAuth2, RBAC, OWASP best practices, PCI/PII complianceI’m passionate about building platforms and teams that both meet and exceed business goals and deliver exceptional customer experiences.
